The color of the plugs isn't the issue, it's the tip of the ground strap that's been melted. The edges should be square, and sharp, not rounded.

Secondly, the heat mark is not visible on the ground straps....clean them up with brake cleaner and we'll have something that tells the real story....

If I had the time and was closer, no problem....

Okay will do now.

So I just came from the machine shop and was talking to them about the engine.

1. They told me they need the pistons, mainly the rings to finish the block. Does that sound right? I'm really with remembering sometimes, but it has to do with the gap on the rings where the ends come together.
2. They also wanted to know how much boost I was planning on running(told them around 15psi) and the compression ratio.
